, Application fled August 2, 1924. Serial No. 729,674.

To aroma may concern:

Be it known that I, Amm- K. LAUREL,

a citizen of the United States, a resident of Detro'r'rt in the county of Wayne and State of Michigam'have invented a certain new and useful Method. for the Production of Deposited-Metal Patterns and -Metal Patproduction of deposited metal patterns in.

tern. Produced by Such Method, of which the. following is a specification.

This invention relates to a method for the which certain parts, ordinarily exposed to wear, are replaced by other metals. Theinvention also relates to a novel form of metal pattern. In metal patterns made by the usual process of the present day, replace I is, generally speaking,

ment of parts is a diflicult thing. For, example, if patterns are made of brass the replacement of any parts exposed to wear by steel would be impractical due to excessive cost. The casting of the pieces in place is also an impractical scheme and is practically never done. It would also be .diificultto solder or screw the pieces in place. While in certain cases such. as replacement, of bosses, it may be racti'calto a certain extent to screw or rivet them in position, it

an impractical procedure to make similar attempts for all purposes.

It is accordingly an object of my invention to avoid these difiiculties in themanufacture'of metalpatterns by substituting certain other metals in exposed portions where wear is ordinarily excessive and. severe inits action on the metal.

In the accompan ing drawings which 7 form part of the specification, there is shown in Fig. 1 a section of a metal pattern as ordinarily made integrally of one metal; Fig. 2 shows a section wherein the exposed boss and flange are formed of a diflerent metalfrom the metal of the castin and Fig. 3 shows .the manner in which the electro-deposition is carried out in the presence of inserted metal parts at the bottom of the laster of Paris mold. 1

In said drawings the replaced metal parts are indicated by numerals 1 and 2, the electrolytic shell by 3, the protective card board or other covering b 4, and the plaster at Paris mold by 5, an the cathode wire accomplishing my object I preferably posited with the ,proceed. by making use of the process described in my previousapplicationfSerial No. 563,188, filed May 24, 1922, in which a method of electro-deposit ien is described for .the manufacture of metal atterns. In carrying out my method I ma e a desired number of molds or casts from the wood or metal pattern that I wish to duplicate, as for example, by making. plaster of Paris casts or other suitable molding material. Thereafter I preparethe molds for depositby connecting the cathode wire. to the-surfaces and providing the latter w'itha conductive coating of carbon. Then I prepare pieces of metals of desired form and com;-

position by machining them to the desired size or otherwise forming-them and'l then place them in the desired position in the mold where they will ultimately form part of the entire deposited pattern. Thereafter the deposition of the metal is carried ing as described in said application, namely,

out in the manner described in my. aforesaid application and when a thickness has been built up include the inserted meta parts.

The pieces inserted may consist of any metal suitable for the particular the pattern is to be put, such as monel metal, brass, bronze, etc. metal used is likely to be bath, the pieces are first suitable resistant metal and thereafter used as above described, for example, if the metal would be steel, which is attacked by an elecsteel, nickel, In case the trolytic bath, itwould be first plated with copper in a cyanide bath in which condition y e osition o f cop er. Alt ough' 'n the 9. ve specification the invention has been particularly set forth with attacked in then plated with some the mold and placed inthe shell of sufiicient. it will, of course,

use to which ro er and the rest of the pattern is finished respect to the manufacture of patterns it is to be understood that it is likewise adapted to the manufacture of cores or core boxes in a similar manner, and therefore in the s eeification and claims Where the Word pet terns is used, it is to be understood thst cores or core boxes are also contemeleted and covered.

As many apparently widely different embodiments of this invention may he made without departing from the spirit thereof, it is understood that it do not intend to limit myself to the specific embodiment above described, except as indicated in the appended claims,

I claim:

1.. A methodi or the production of do posited metal patterns consisting in me! a mold of the desired form, preparing r electro deposition placing therein metal parts and depositing metal in the molds to form the pattern.

2. A method for the production of deposited metal patterns consisting in making a mold of the desired form, preparing it for electro-deposition, placing; therein metal parts formed of deposited metal, and de- 7 positing metal in the mol is to form the pattern m 3. The process of claim l m which the inserted metal parts are previously coated parts made of hard metals in s newest posited metal patterns consisting in making a mold of the desired form, preps ing it for electro-deposition, placing therein metal 1 a posie pattern tion as to lie in the portions 0: which are eventually to be exp. to heavy Wear, andthen'depositing met e molds to form the pattern with metal parts embedded in the same.

5. A metal pattern consis relatively thick deposited pable of being used Without said shell having embedded hard metal at places Where subjected to heavy Wear.

6. A. metal pattern consist relatively thicl: deposited in pable of being used Withon said shell having embedded the hard metal at places Where it! subjected to heavy Wear, tit molding surfaces of the pattern being in finished and exact form without having been machined, filed or scraped.

In testimony that 1 claim foregoing, havehereunto set my hand a; 0' July, 1924-.
